If you do a lot of traveling, check out Aero Beds. My son outgrew the pack and play quickly. Aero Bed makes a toddler bed that inflates in a minute or so, and is ressessed in the middle so a child cant roll out easily. It comes with a carry sack and when rolled up is about the size of a sleeping bag. If youre going to check it with luggage on a plane you might want to get a heavier duty bag to put it in as our bag has a hole worn in it now. We take ours everywhere-grandparents, WDW, trips, etc. If space is an issue (like in a cruise ship cabin), we also picked up a ready bed which is a sleeping bag that inflates. Not quite as comfy as the aero bed, but it works and is smaller to haul (our son carries it). When we first used them, our son would not settle down right away unless he was really tired. He kept getting up and walking around. If you get one, make sure to have your child sleep in it before you trip to get used to it.
